Azure Kubernetes - 'az acs create' 并超过免费帐户配额
Azure Kubernetes - 'az acs create' and exceeding free account quota
尝试为 Azure 容器服务做与我的 MongoDB on GKE blog post 等效的事情，但在第一个障碍上失败了。我的博文基于使用每个云提供商的免费 tier/account 中可用的配额，以帮助新用户在继续付费层之前评估选项。但是，在创建了一个 Azure 免费帐户后，我似乎无法创建一个保持在 "core limits" 以下的 k8s 集群（在这种情况下，我假设意思是保持在相当于 "vCPUs" 的免费阈值以下）。
当我运行关注：
az acs create --orchestrator-type kubernetes --resource-group MongoResourceGroup --name MongoK8sCluster --generate-ssh-keys
结果是：
Deployment failed. { "code": "BadRequest", "message": "An error has occurred in subscription 0657d162-d822-48f5-bbe9-4bcaac4f40e4, zesourceGroup: MongoResourceGroup request: Provisioning of resource(s) for container service MongoK8sCluster in resource group MongoResourceGroup failed. Message: {\n \"code\": \"QuotaExceeded\",\n \"message\": \"Provisioning of resource(s) for container service MongoK8sCluster in resource group MongoResourceGroup failed. Message: Operation results in exceeding quota limits of Core. Maximum allowed: 4, Current in use: 0, Additional requested: 8.. Details: \"\n }. Details: <no value>."
我试图指定一种较小类型的 VM，但我似乎不太明白：
az acs create --orchestrator-type kubernetes --resource-group MongoResourceGroup --name MongoK8sCluster --agent-vm-size Standard_A0 --generate-ssh-keys
Deployment failed. { "code": "BadRequest", "message": "An error has occurred in subscription 0657d162-d822-48f5-bbe9-4bcaac4f40e4, resourceGroup: MongoResourceGroup request: Provisioning of resource(s) for container service MongoK8sCluster in resource group MongoResourceGroup failed.

有什么建议可以让 k8s 示例项目的核心计数减少到足以在免费帐户阈值之内吗？
根据此处的文档https://docs.microsoft.com/en-us/cli/azure/acs#create 默认代理计数为 3，默认主虚拟机大小为标准 D2_v2。这使得核心要求为
3(agents)*1(core) + 1(master)*2(core) = 5
因为你有 4 个核心可用，你应该尝试设置：
1. agent-count to be 3
2. agent-vm-size to be Standard_A0
或
1. agent-count to be 1
2. agent-vm-size to be Standard_D11_v2
我更喜欢选项 (2)，因为这会在代理节点上提供足够的内存和 IOPS。保持 master-vm-size 默认为 Standard D2_v2 因为 etcd 和 kubenetes 容器需要足够的内存来运行。
使用以下配置会有帮助。
- --master-count 1 => Standard_A2 (2 cpu) => 2 cpu
- --代理计数 2 => Standard_A1 (1 cpu x 2) => 2 cpu
此配置将在免费帐户限制内创建集群
az acs create -n "your-kubernetes-cluster" -g your-resource-group --master-vm-size Standard_A2 --agent-count 2 --agent-vm-size Standard_A1 --dns-prefix kube --orchestrator-type kubernetes --debug
